Gimbal, Gremlin Prodigy

Legendary Creature — Gremlin Artificer

Artifact creatures you control have trample. At the beginning of your end step, create a 0/0 red Gremlin artifact creature token. Put X +1/+1 counters on it, where X is the number of differently named artifact tokens you control.

You are what you eat, and everything he'd eaten was brilliant.
